Intellectual Communications and Contemporarly Technologies Alternatives of the Science Libraries

(Summary of: Varbanova-Dencheva, K. Intellectual communications and contemporarly technologies. Alternatives of the science libraries. Sofia, Marin Drinov academic publishing house. 2003, 114p. ) The new technologies and the globalization are the factors which have brought essential changes in human society and its environment. The unceasing dynamic changes imposed new strategies for survival and prosperity of institutions and people in the new conditions. The spheres with greatest potential for achieving competition priority are compatible to the fastness of research results implementation in each field of human activity. The extended knowledge requires narrower specialization as well as interdisciplinarity to solve the arising problems. The new research fields and trends are a synthesis of science and high technologies determined by the new discoveries. The present study aims at finding answers to the questions about the place of science library in the dynamic restructuring of research environment. The necessity of transformation of the scientific library’s genetically set functions from a guardian of the achieved knowledge to an active participant in the creation of new knowledge is a natural consequence of the processes and tendencies of the social medium. The priorities of Europe and USA for intensive creation of knowledge economics are at the first place and this requires intensification of that research an integral part of which are the new communications realized at a new technological level.

Polluting production – environmentally sound alternatives; A general model of production externalities

With the determination of principal parameters of producing and pollution abatement technologies, this paper quantifies abatement and external costs at the social optimum and analyses the dynamic relationship between technological development and the above-mentioned costs. With the partial analysis of parameters, the paper presents the impacts on the level of pollution and external costs of extensive and intensive environmental protection, market demand change and product fees, and not environmental protection oriented technological development. Parametrical cost calculation makes the drawing up of two useful rules of thumb possible in connection with the rate of government in-terventions. Also, the paradox of technological development aiming at intensive environmental protection will become apparent.

Sustainable consumption: from escape strategies towards real alternatives

Better sustainability policy is supposed to lead to better sustainability performance. Nonetheless, recent research predicts further growth of the ecological footprint and stable ecological deficit in Europe and North America despite their impressive policy efforts (Lenzen et al. 2007) [1]. Similarly, individual strategies result in somewhat reduced load for committed consumers, but this reduction cannot offset the total impact of the socio-economic configuration: consumers in higher income countries tend to pollute more. Comitted consumers "offset" a part of their environmental load by carrying out green purchases. A radical change assumes a change in lifestyle (Shove, 2004) [2]. The conference paper is the first step of the study that aims at measuring the significance of attitude elements as compared to the significance of the socio-economic system on different elements of consumption and environmental aspects This paper focuses on measuring the ecological footprint impacts of consumption in different product groups as well as in different income groups of the society.

A közgazdaságtan és a szociológia határán - az identitás-gazdaságtan által felvetett elméleti kérdések (On the borders of economics and sociology. Theoretical questions raised by identity economics)

A tanulmány az identitás-gazdaságtan megközelítését és az általa felvetett elméleti kérdéseket kívánja bemutatni. E tan kiinduló tétele George A. Akerlof és Rachel E. Kranton szerint az, hogy a közgazdaságtanban használt hasznosságfüggvénybe be kell emelni az emberek énképének és az ezzel kapcsolatos egyéni mérlegelésnek a szempontjait. Ezt az indokolja, hogy az emberek társadalmi csoportokhoz/kategóriákhoz tartoznak, amelyekhez normarendszer társul, azaz ha viselkedésükkel megsértik a normákat, akkor önképük sérül, és ezáltal csökken a hasznosságuk is. A tanulmányban bemutatjuk, hogy ez a szemlélet az embereket "túlszocializált" társadalmi szereplőkként mutatja be, akik kevéssé reflektálnak a helyzetükre. További kérdéseket vetnek fel az elmúlt években végzett szociálpszichológiai és viselkedés- gazdaságtani kísérletek, amelyek rámutatnak, hogy az identitás- gazdaságtani elmélet egyik alapját jelentő normák erősen függnek szituációs tényezőktől. _____ The paper introduces the approach of identity economics and the theoretical questions raised by its arguments. According to Akerlof and Kranton, individual identity and personal calculations in relation to this identity should be incorporated into the utility function applied in economics, so that people are placed in social categories that involve normative systems. In line with this, if their actions breach the social norms, this affects negatively their self-image, so in turn decreasing their utility. The paper argues that this approach presents humans as "overly socialized" social actors who do not reflect on their situation. Further questions could be raised by experiments in social psychology and behavioral economics conducted in recent years. The results highlight the fact that the norms which serve as the basis for the theory of identity economics depend strongly on the context and given situation.

A szervezeti identitás meghatározása, elemei és menedzselése (Defining of organizational identity and its components and management)

Jelen cikk a szervezeti identitás különböző tudományos értelmezéseit, elemeit mutatja be és kapcsolja össze a gyakorlattal. A szerzők értelmezése szerint a szervezeti identitás nem azonos a köznyelvben elterjedt arculattal (sem image-zsal), hanem egy holisztikus, menedzsment-szakirodalmakon átívelő fogalomként értelmezhető, mely a külső tényezők hatására a szervezeti kultúra és a szervezeti stratégia alapján alakítható ki. A szervezeti identitás három alkotóelem-csoportból áll (nevezhetjük ezt identitásmixnek is): a munkáltatói márkázásból, az integrált marketingkommunikációból és a vizuális identitásból. Mivel a változó környezet szükségessé teszi, a szervezeti identitás menedzselése egy véget nem érő „spirálfolyamat”, mely a felmérés, a meghatározás, a bevezetés és értékelés szakaszok ismétléséből áll addig, amíg az ideális identitás ki nem alakul. Melyet talán soha nem ér el a vállalat. _____ In this article the different scientific interpretations and elements of organizational identity are presented and combined with practice. According to the authors’ interpretation the organizational identity is not the same as the corporate image, but it can be interpreted as a holistic management literatures panning notion which can be formed by the effect of external factors on basis of the organizational culture and organizational strategy. The organizational identity consists of three component-groups (also called this identity mix) the employer branding, integrated marketingcommunications and visual identity. Due to the changing environment makes it necessary the management of organizational identity is a never-ending ”spiral process”, which consists of repetitions of the survey, the definition, the introduction and the assessment phases until the ideal identity will be formed. Which may be never achieved by the corporate.

A környezeti identitás szerepe a környezettudatos magatartásban – a mérési lehetőségek értékelése

A környezettudatos viselkedés kialakulásának egyik előfeltétele a természethez való tartozás átélése1. A természet közelségének érzésével nő az empátia és a segítő szándék a természet irányába, elősegítve a környezettudatos viselkedés kialakulását. A környezeti identitás a személyiség és a természet közötti kapcsolatot mutatja, a nem ember által alkotott környezettel való összekapcsolódás érzését, amely hatással van az egyének világészlelésére és a természetben való viselkedésére is. Jelen cikk a környezeti identitás koncepciójának értelmezését, relevanciáját és alkalmazásának lehetőségeit járja körbe a környezetbarát viselkedés vizsgálatában, mint a természettel való kapcsolat elemzési keretét. Ha a természethez való kötődést az egyénben tudatosnak tekintjük, akkor közvetlen (explicit vagy direkt), ha tudattalan jelenségként tekintjük, akkor közvetett (implicit vagy indirekt) mérések alkalmazhatók. A szerző írásában bemutatja a környezeti identitás implicit mérésére alkalmas Implicit Asszociációs Teszt (IAT) Nature változatát, és a módszer alkalmazásával készült empirikus kutatás eredményeit, amelyeket explicit mérésekkel vet össze. Az implicit eredmények alapján hasonló mértékben kötődünk a természeti és az épített környezethez, és a kötődés mértékének nincs hatása a viselkedésre. Az explicit mérésű környezeti identitás ugyanakkor közepesen erős kapcsolatot mutat a környezettudatos viselkedéssel. A cikk célja az eltérő eredmények értékelése és adaptálása.

Multikulturális szervezet és identitás (Multicultural organisation and identity)

Jelen cikk célja a multikulturális szervezet fogalmának újraértelmezése, amelyet a következő lépések mentén valósít meg: (1) a releváns tudományterületek azonosítása – szervezeti kultúra és munkahelyi diverzitás – és komplementáris jellegük bizonyítása (ki)alakulásuk történeti ívének párhuzamos bemutatása révén, (2) a tudományterületek történeti alakulását hűen megragadni képes, rendszerező elméleti keret kiválasztása és bemutatása, (3) a multikulturális szervezet főbb dimenzióinak azonosítása, valamint (4) a multikulturális szervezeti kontextus meghatározása a fentiekben meghatározott dimenzióknak az elméleti keretben való értelmezése révén. ______ The aim of this article is to redefine the multicultural organizational concept, which is going to be accomplished along the following steps: (1) identifying the relevant disciplines – organizational culture and workplace diversity – and demonstrate their complementary character through a brief review of their roots and development, (2) presenting the organizing theoretical, which helps me to capture the development of the above mentioned literatures (3) identifying the main dimensions of the multicultural organization and (4) defining the multicultural organizational context based on the delineation of the above recognized dimensions within the organizing theoretical frame.

Alternatives to steel grid bridge decks

Most of the moveable bridges use open grid steel decks, because these are factory assembled, light-weight, and easy to install. Open grid steel decks, however, are not as skid resistant as solid decks. Costly maintenance, high noise levels, poor riding comfort and susceptibility to vibrations are among the other disadvantages of these decks. The major objective of this research was to develop alternative deck systems which weigh no more than 25 lb/ft2, have solid riding surface, are no more than 4–5 in. thick and are able to withstand prescribed loading. Three deck systems were considered in this study: ultra-high performance concrete (UHPC) deck, aluminum deck and UHPC-fiber reinforced polymer (FRP) tube deck. UHPC deck was the first alternative system developed as a part of this project. Due to its ultra high strength, this type of concrete results in thinner sections, which helps satisfy the strict self-weight limit. A comprehensive experimental and analytical evaluation of the system was carried out to establish its suitability. Both single and multi-unit specimens with one or two spans were tested for static and dynamic loading. Finite element models were developed to predict the deck behavior. The study led to the conclusion that the UHPC bridge deck is a feasible alternative to open grid steel deck. Aluminum deck was the second alternative system studied in this project. A detailed experimental and analytical evaluation of the system was carried out. The experimental work included static and dynamic loading on the deck panels and connections. Analytical work included detailed finite element modeling. Based on the in-depth experimental and analytical evaluations, it was concluded that aluminum deck was a suitable alternative to open grid steel decks and is ready for implementation. UHPC-FRP tube deck was the third system developed in this research. Prestressed hollow core decks are commonly used, but the proposed type of steel-free deck is quite novel. Preliminary experimental evaluations of two simple-span specimens, one with uniform section and the other with tapered section were carried out. The system was shown to have good promise to replace the conventional open grid decks. Additional work, however, is needed before the system is recommended for field application.

Adult Alternatives for Social Drinking: A Direction

In their survey/study - Adult Alternatives for Social Drinking: A Direction - by John Dienhart and Sandra Strick, Assistant Professors, Department of Restaurant, Hotel and Institutional Management, Purdue University, Dienhart and Strick begin with: “Changes in consumer habits have brought about a change in the business of selling alcoholic drinks and have impacted upon hotel food and beverage operations. The authors surveyed a sample of hotel corporate food and beverage directors to ascertain how they are handling this challenge.” Dienhart and Strick declare that the alcoholic beverage market, sale and consumption thereof, has taken a bit of a hit in contemporary society. “Even to the casual observer, it's obvious that the bar and beverage industry has undergone a great deal of change in the past few years,” say the authors. “Observations include a change in the types of drinks people are ordering, as well as a decrease in the number of drinks being sold,” they qualify. Dienhart and Strick allude to an increase in the federal excise tax, attacks from alcohol awareness groups, the diminished capacity of bars and restaurants to offer happy hours, increased liability insurance premiums as well as third-party liability issues, and people’s awareness of their own mortality as some of the reasons for the change. To quantify some empirical data on beverage consumption the Restaurant, Hotel, and Institutional Management Department of Purdue University conducted a study “… to determine if observed trends could be documented with hard data.” In regards to the subject, the study asks and answers a lot of interesting questions with the results presented to concerned followers via percentages. Typical of the results are: “When asked whether the corporation experienced a change in alcoholic sales in the past year, 67 percent reported a decrease in the amount of alcohol sold.” “Sixty-two percent of the respondents reported an increase in non-alcoholic sales over the past year. The average size of the increase was 8 percent. What Dienhart and Strick observe is that the decrease in alcoholic beverage consumption has resulted in a net increase for non-alcoholic beverage consumption. What are termed specialty drinks are gaining a foothold in the market, say the authors. “These include traditional cocktails made with alcohol-free products, as well as creative new juice based drinks, cream based drinks, carbonated beverages, and heated drinks,” say Dienhart and Strick by way of citation . Another result of the non-alcoholic consumption trend is the emergence of some novel marketing approaches by beer, wine, and spirits producers, including price increases on their alcohol based beverages as well as the introduction of faux alcoholic drinks like non-alcoholic beer and wine. Who or what is the big winner in all of this? That distinction might go to bottled water!
